To all whom, it may concern:

Be it known that I, ALFRED F. Masnnr, a citizen of the United States, residing in. the borough of Manhattan of the city of New York, in the State of New York, have invented certain new and. useful Improvements in Radiators for Automobiles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to radiators for particularly with that type of radiator in which air currents are established and maintained by means of a fan and are caused to pass over the water tubes and thereby cool the water before it passes to the cylinder jackets. In this typepof radiator the tubes are arranged in bundles of substantially cylindrical outline and the fan is mounted within the bundles and in substantially co-axial relationship thereto, so that the cooling air travels into the space within the bundles in a direction arallel to the axis thereof and is there caug t up by the revolving fan blades and thrown outwardly through the tubes in a direction radially thereto. By reason of the dispersion of the air in this manner, it will be evident that a radiator of this character will deprive the motor of the air which would otherwise pass thereover and have a cooling action, unless the radiator is so con- Structed as not to interfere with the natural supply of air to the motor. It is the principal object of this invention so to construct and mount the improved radiator that the motor will receive the entire supply of air which normally passes through the bonnet of a car while it is moving forward while it will, at the same time, force an ample supply of cooling air across the bundle of water tubes and so insure the effective cooling of these tubes at all times. A further object is to provide a radiator which shall perform lllt additional function of creating a onstant draft through the body of the car about the drivers seat and particularly under the dash. This draft not only cools the space referred to :1 ml thereby dissipates the heat which nornnllly ri es under the dash, but also insures an adequate supply of coolingmir for the wnlcr tubes. lo realize the stated objects of the invention the improved radiator is mounted just forward of the dash and between it and the motor space so that the fan is exposed both to the motor space and to the space behind the dash and takes its cooling air from the tubes from both sides thereof. This disposition of the radiator is especially effective in assisting the natural draft of air through the motor bonnet which is created normally by the forward movement of the car alone. The in vention is further concerned with certain details of construction of the radiator whereby it is made very compact, inexpensive to manufacture, readily accessible for repair or replacement of parts and attractive in appearance. One embodiment of the invention will now be described with reference to the accompanying drawings in which Figure 1 is a fragmentary View, partly in vertical section and partly in side elevation of a portion of a car equipped with the improved radiator, and showing particularly the relation thereof the drivers seat.

Fig. 2 is a detail view on an enlarged scale. partly in side elevation and partly in vertical section, of the improved radiator, the water tubes being broken out in the in terest of clcarness.

Fig. 3 is a detail view in elevation of the improved radiator, part of the casing therefor being broken away to show the disposition of some of the tubes. the view being taken from within the motor bonnet.

The automobile body a may have mounted on the forward end of its chassis 5 its motor 0, which may be inclosed, as usual, by a motor bonnet (Z, the forward end of which may be open to permit the free inflow of air during the forward movement of the car. 0n the chassis I of the car or motor support 6 thereof may be mounted the improved radiator, indicated generally at e, and having at its base suitable feet (2', through which and the motor support I) may be passed securing bolts), whereby the radiator as a unit may be demounicd. In Fig. 3 the motor is omitted in the interest of clearness, but in Fig. 1 it is clearly shown as bein secured to the underside of the member by the bolls. The radiator e, includes a casin e, tlnsides of which may be stamped up rom to the motor bonnet and a singleshcet of metal or which ma be built for the outflow of air as will appear later. The c sing of the radiator may be strengthcued as may be necessary by suitable angle plates 9. Within the casing 6 is builtup the radiator structure proper consisting preferably of two substantially semi-cylindrical bundles of water tubes h, the ends of which are expanded into plates 6, each semicylindrical bundle of tubes with the end plates forming a unitary and detachable section. The plates 1' are secured to water reservoirs k and Z disposed respectively at the to and bottom of the radiator and forme with inclined sides to receive the plates i, and detachable ends to permit access to the tubes it. These plates may be detachably secured to the flanged side Walls of the reservoirs k and Z by suitable bolts m. The upper reservoir is may be provided, as usual, with a cap 70' to permit the filling of the radiator, and with an inlet pipe in throfigh which the water passes from. the jacket of the motor a through a duct 0, as will be understood. The lower reservoir Z also may carry an outlet passage 1 through which the water may pass from the radiator to the jacket of the motor a through a suitable connection 0 thus completing the water circuit.

From the description given, it .will be understood that the bundles of tubes h with the reservoirs k and Z form an annulus, the space within which is exposed to the air on both sides of the radiator, that is, that with in the motor bonnet d and that within the dash of the car body a. The bundles of tubes h and the reservoirs 7c and Z may be inclosed by the front and rear plates of the casing for the radiator, but these plates do not ex tend inwardly to a suflicient extent to cut off the free spacetwithin the annulus. Within this free space and substantially in the plane of the tubes h is mounted a suitable air fan which may be formed with a hub n. mounted on suitable bearings n and carry ing fan blades n, which ma be disposed in the most effective relations ip to the hub. In practice it has been found desirable to have these fan blades n tangential to the hub 11., although it is to be understood that other arrangements may be used without departin from the invention. A simple and practicofform of fan is illustrated and will be described in some detail. The supporting shaft 0 of the fan may be convenientlymounted in diametrical braclo ets p and which may be bolted to the end faces of t e reservoirs k and Z and on the outer faces of the end plates of the casing e for the radiator. One ofthe brackets g is curved a ipreciably to receive the driving belt '1' for t e'fan and the driving pulliiyn over which thebelt asses. On the fixed shaft 0 is carried a s eeve 0' on which are formed recesses for the roller bearings 0 extend substantially position 0.

these bearings bein embraced by race rings 0 on which rests tie tubular hub it proper for the fan. The surface of this hub, in the illustrated enllmdiment, is tapered from the middle in both directions, as shown by dotted lines at 11 in Fig. 3, and slotted at suitable intervals on. its circumference to receive the fan blades n, which may be detachably held in position by set screws a. As the fan blades n" are of substantially the same Width as the bundles of tubes it and have their outer ends in juxtaposition to the inner tubes of these bundles, it will be understood that a very strong current of air will be thrown through these bundles of tubes when the fan is rotated.

In the interest of safety, the exposed openings in the front and rear walls of the casing e of the radiator and the openings c in the side walls a thereof may be covered with suitable wire mesh 8 which will rcvent accidental injury through contact 0 a person with the revolving fan, will prevent the entrance of foreign objects into the casing and will afi'ord a sightly appearance to the radiator.

Thus far, it has been sought only to describe the structure by which the objects of the invention are realized but it is to be remembered that of equal importance with the structural features of the radiator is the disposition thereof with respect to the other parts of the car and the novel theory of operation on which the invention is based to a great extent. In the first place, a radi cal departure from known. constructions is marked by the disposition of the radiator between the motor bonnet and the dash so that the fan is exposed to the'air within the motor bonnet and to the air under the dash and around the drivers seat. By reasonv of this disposition, the free passage of air into the space under the motor bonnet is not interfered with in any we; so that the motor has the advantage of to receiving a full cooling action from this natural inflow during the forward movement of the car. In revious constructions this natural inflow 0 air to the motor has been interfered with. Again, this flow of air through the motor bonnet is enhanced by the improved radiator and the full effect thereof received b the motor because of the disthe fan at the rear of the motor and in. free communication therewith. 'It is to be noted, however, that the cooling of the water tubes it through the radial dis persion of the air received by the fan is not brought about entirely by that air which has passed through the motor bonnet but an equal supply of absolutely fresh air may be drawn in by the fan from the space under thedash of the car a, since the fan is not only exposed to the bonnet cl but is also exposed to thespace around the drivers seat.

This induced draft around the space of the drivers seat is highly desirable for other reasons than the cooling of the bundles of tubes it because this space under the dash usually becomes very warm, especially Where fore-doors are used. The present invention, therefore, embodiesmeans for cooling the forward end of the body a of the car. The action take all of the air which flows thereto from each side thereof in directions substantially parallel with the axis of the fan and to throw the air outward in a substantially radial direction and cause it to pass through the bundles of tubes h and out through the openings 6* formed in the side walls of the casing e? of the radiator. The air thus expelled will be somewhat warm after passing over the Water tubes h, but this warm air at this part of the body a of the car wil l not be objectionable as the dash or cowl will throw it away from the body and the passengers in the car.

As pointed out before, the improved radiator e may be detached as a unit by loosening the bolts f or, where desired, the radiator may remain in position on the motor support 6 and be removed with the motor as a unit.

In repair or replacement of any of the parts of the improved radiator, it will be clear that ready access is by removal of any one of the constituent parts of the casing e of the radiator. By loosening the bolts m in any one of Hm of the fan is such as to afi'orded thereto,

lates i the plate with the tubes It may be etached readily from the abutting flanges of the inclined walls of the reservoirs in, Z. Further, either one of the brackets 12, g may be demounted by loosening its securm bolts and the fan thereafter readily remove from the sition within the bundles of tubes h.

Mii difications of the details of construction will suggest themselves to those skilled in the art, but all suchmodifications are .to be deemed within the spirit of this invem tion provided they fall within thescope of the a pended claim.

I clitim as my invention:

A radiator for automobiles coin rising a. casing having its end and side we ls perforated, water reservoirs, semi-cylindrical bundles of tubes secured to the reservoirs, plates into which the ends of the tubes are'expended, the reservoirs being provided with inclined and flanged side walls to receive said lates, means to secure the plates detachably to the flanges, a fan rotatably mounted within the bundles of tubes and in the plane thereof, and supports for the fan extemiing diametrically across the circular bundles and secured detachably to the outer sides of the radiator.
